56th Independent Mixed Brigade

The 56th Independent Mixed Brigade was an Imperial Japanese Army unit of World War II. It was raised in June 1944 to reinforce the defences of Japanese-occupied Borneo, and was initially stationed in the north-east of the island. In early 1945 most of the brigade's units were ordered to move to the Brunei Bay area of west Borneo, with the brigade's personnel subsequently making a difficult march across the centre of the island.

During June and July 1945 the 56th Independent Mixed Brigade saw combat against Australian forces in the Borneo Campaign. Its units were greatly under-strength at this time due to the casualties suffered while moving across Borneo, and the elements which engaged Australian forces were rapidly defeated. The remainder of the brigade withdrew into central Borneo, and surrendered to the Australians following the end of the war.
